Robotdigg actually came through with a delivery of 2 GT2 - 20 tooth pulleys and a length of GT2 belt. Everything looked good, set screws were there, even a little allen wrench included. For that price you can't beat it if it holds up after use. We will see how Chinese parts work (there were no obvious flaws).

Shipping: Took about 2.5 weeks.

Response: His response time was pretty quick, even updated with a tracking number when I asked.

Website checkout is a little weird but overall it was a smooth process.

Just got my orders from Robotdigg today. Took about 2.5 weeks to get stateside. Everything looks legit and the motors work flawlessly. Plus they came with connectors which goes into the Printrboard. Despite the non-conventional way of ordering, they follow through as promised. Definitely worth checking out!

I'm glad to hear you guys are having good experiences with your orders. That gives me a lot of faith in receiving my order! I still have a couple weeks for my motors to be built before they ship but the good experiences are getting me more excited. I'll be sure to post pictures of the 500mm Acme TR8*8 Nema 17 beauties once I have them in my hands (and finish drooling!).

So I have been printing with my motors for a week and a half now....I love them! They work smoothly, layer heights are precise and the 8mm lead allows the motors to easily lift the x-carriage without any issue. I would HIGHLY recommend the motors to anyone willing to spend the $$. You can save a lot of time and money by not going custom as I did. The reason I ordered them custom was so that I could use the anti-backlash nuts that Ribotdigg sells. If you don't mind sourcing the nuts from another place, you can order the pre-made models of Acme lead screw Nema 17's they sell.
